About this event
For one weekend in October more than two hundred buildings across Barcelona open their doors for nothing: private apartments, workshops, institutional interiors and modernista landmarks you normally only see from the street. Running since 2010, the festival also puts on guided itineraries and talks. Some spaces are free-flow within set hours; guided routes need advance sign-up.
Why we picked it
The one weekend a year when the city's closed doors open, entirely free — and the Saturday falls just inside this window.
Free entry
